TRANSMITTER DESCRIPTION

1. Sound Settings

These settings enable the user to set the v

olume of audio signals at the signal inputs for each channel.

Note: If y

ou set the volume too high, the sound may be distorted.

Note: If volume setting is too high when the system operates near speakers, it may result in Larsen effect

in the speakers.

2. LED Display

Displays for each channel indicate all indications necessary to a proper function of the HF system:

- frequency being used

- number of the channel corresponding to the frequency being used

- RF reception level

- AF audio signal level

- Receiving aerial indicator: 1 or Il

- Sound attenuation (cut-off) indicator: Mute

3. Frequency Confirmation Button

This button allows y

ou to confirm the frequency selected. In addition, it allows you to confirm receiver

settings.

The button is also used to lock a working frequency.

USB 7392 - 7393

4. Frequency Selection Button (Down)

This button (Down) allows you to select a working frequency of the receiver.

It also allows you to change receiver settings.

Note: To ensure a proper function of the HF system, the transmitter (handheld microphone or belt

case) and the receiver must be set to the same working frequency.

5. Frequency Selection Button (Up)

This button (Down) allows you to select a working frequency of the receiver.

It also allows you to change receiver settings.

Note: To ensure a proper function of the HF system, the transmitter (handheld microphone or belt

case) and the receiver must be set to the same working frequency.

6. On/Off Button

This button allows you to turn the receiver on or off.

1. A

-Aerial Connector

Connect the aerial (supplied with the microphone set) to this socket.

2. Power Supply Connector

Connect the DC 12V power supply (supplied with the microphone set) to this socket. Note: Do not

connect other types of power supply (an AC one or a DC one supplying more than 12V). Otherwise,

it may result in damage to the receiver.

3. B-Channel Symmetrical Output

This socket is an audio output for the B-channel of the receiver. Connect this output to the micropho-

ne input of y

our audio mix

er or directly to an input of y

our amplifier

.

Note: It is a symmetrical output. Therefore, use a symmetrical cable and XLR connector.

4. Mix Asymmetrical Output

This sock

et is an audio output mixing both channels. Connect this output to the microphone input of

y

our audio mix

er or directly to an input of y

our amplifier.

Note: It is an asymmetrical output. Therefore, use an asymmetrical cable and 6.35mm jack.

5

. A-Channel Symmetrical Output

This socket is an audio output for the A-channel of the transmitter. Connect this output to the micro-

phone input of your audio mixer or directly to an input of your amplifier.

N

ote: It is a symmetrical output. Therefore, use a symmetrical cable and XLR connector.

6. A-Aerial Connector

Connect the aerial (supplied with the microphone set) to this socket.

PUTTING THE RECEIVER INTO OPERATION

- Connect both aerials to the sockets designed for them (A and B).

- Direct them to a 90Y direction in relation to the receiver.

- Connect the DC 12V power supply to the power supply connector.

Warning: Do not connect other types of power supply (an AC one or a DC one supplying more than

12V). Otherwise, it ma

y result in damage to the receiver..

- Set the volume adjustment buttons for each channel to minimum and, then, press the On/Off but-

ton and hold it depressed for 1 to 2 seconds.

- By using the Up and Down buttons, set working frequencies for each channel and, then, confirm the

frequencies by pressing the Set button.

Note: Receiver are specifications are included below in this operating manual.

- To turn the receiver off, press the On/Off button (2) and hold it depressed for 1 to 2 seconds. The

LCD will show “SYSOFF”.

LCD DISPLAY DESCRIPTION

1. RF Indicator

It indicates the level of RF signal (the signal received from the microphone).

2. AF Indicator

It indicates the lev

el of AF signal (channel output signal).

3. Working frequency

It indicates the frequency used in operation.

4. A Aerial Indicator

As it is a selective reception receiver, it chooses the aerial via which the reception is the best. If the

display shows 1, it means that reception is carried out by means of the A aerial.

5. B Aerial Indicator.

As it is a selective reception receiver, it chooses the aerial via which the reception is the best. If the

display shows Il, it means that reception is carried out by means of the B aerial.

6. Sound Attenuation Indicator

This logo is to inform you of the fact that the unit operates in the “mute” mode (that means that no

sound is at the channel output – either nobody speaks into the microphone or the receiver frequen-

cy differs from the transmitter frequency).

FREQUENCY SETTING CHANGE

- To obtain the display required, press the Set button.

- By using the Up & Down buttons, select another channel. The display starts blinking.

- Press the Set button again to confirm your selection.

Change between Frequency/Channel Number displaying:

- Press the Set button and hold it depressed until the LCD shows "DISPLAY".

SENSITIVITY SETTING

Press the SET button and hold it depressed until the L

CD shows “LOCK”.

- After 2 to 3 seconds, the display will show "XX* dB" ( * the value depends on particular settings).

The value is to inform you of the level of the receiver sensitivity.

- The sensitivity setting allows you to set a resistance of the receiver against interferences. The value

can be set within r

ange from 0 to 40dB

. The higher the v

alue, the higher is the resistance against

interferences. The lower the value, the lower is the resistance of the receiver against interferences.

Standard value is 15dB.

TRANSMITTER LOCKING

-

Press the SET button and hold it down until the LCD shows “LOCK”.

- The display will show either “LOC ON” or “LOC OFF".

(

LOCK ON means that the system is locked at a frequency. Frequency setting cannot be changed, and the

- Press the Set button again to confirm your selection

WARNING

1. If the receiver is turned on, showing cc Un LOCK" on the display, or the red LED indicator on the trans-

mitter is blinking, it means that the receiver or transmitter is out of operation. In that case, refer to your

dealer.

2. If you use more UHF systems at the same time, set the frequency of each system as far from the

other frequencies as possible to avoid interferences between the systems.

3. When inserting batteries into the transmitter (handheld type or belt case), ensure their proper polari-

ties; otherwise, it may result in damage to your transmitter.

4. Set a proper sensitivity of the receiver to obtain the best possible reception.
